Miley Cyrus used some very un-Disney language last night to put the smackdown on a couple of charlatans posing as her friends Dakota and Elle Fanning on the social media site. Seems someone (or ones) has been posting as the famous sisters, to the tune of 36,000 and 14,000 followers respectively. (Fake Dakota and Elle both love Hello Kitty, by the way.)

Cyrus told her 10.6 million fans to follow the sisters (whose accounts at that point were verified) - and then realized that, oops, those aren't the musings of les filles Fanning.
